Heat Treatment Affects Epicuticular Wax Structure and Postharvest Calcium Uptake in 'Golden Delicious' Apples

‘Golden Delicious’ apples (Malus domestica Borkh) were pressure-infiltrated at harvest with a 4% CaCl2 solution either without prior heat treatment or following 4 days at 38C. Examination of the apple surfaces from both treatments by low-temperature scanning electron microscopy revealed that heat treatment changed the pattern of epicuticular wax. The epicuticular wax of nonheated fruit exhibite...

Defects segmentation on ‘Golden Delicious’ apples by using colour machine vision

A method based on colour information is proposed to detect defects on ‘Golden Delicious’ apples. In a first step, a colour model based on the variability of the normal colour is described. To segment the defects, each pixel of an apple image is compared with the model. If it matches the pixel, it is considered as belonging to healthy tissue, otherwise as a defect. Two other steps refine the seg...

Influence of Apples on Population Density, Body Weights, and Reproductive Organ Weights in Pine Voles

Consumer evaluation and quality measurement of fresh-cut slices of ‘Fuji,’ ‘Golden Delicious,’ ‘GoldRush,’ and ‘Granny Smith’ apples

We compared the eating quality of a new apple cultivar, ‘GoldRush,’ with ‘Golden Delicious’ (one of its parents), ‘Fuji,’ and ‘Granny Smith’ (the latter two often used for fresh-cut apple slices). We also compared a commercial with an in-house processing treatment, NatureSeal for apples and Produce Quality and Safety Laboratory (PQSL), respectively. Intact apples that had been stored for about ...
